Specification of Letters Patent.

Patented Mar. 14,1916.

Application filed July 21, 1914. Serial No. 852,267.

This invention relates to spring heels, and

it has for its object to produce a resilient device of simple and improved constr tion which may be readily applied to bo dfi s and shoes in the process of manufacture and which may belikewise readily applied to boots and shoes already made.

A further obJect of the invention is to improve the construction of the resilient device and to enable adjustment of the heel supporting fected.

With these and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in theclaim.

In the accompanying drawingv has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claim may be resorted to when desired.

In the drawing, Figure 1 is a vertical sectional view of the heel portion of a shoe equipped with the invention. Fig. 2 is a plan view of the heel plate detached. Fig. 3 is a side elevation showing the heel plate and related parts detached and separated. Fig. 4 is a perspective detail view of the spring. Fig. 5 is a sectional view illustrating a modification.

Corresponding parts in the several figures are denoted by like characters of reference.

The "shoe heel 15 is provided with a cylindrical recess 16 extending between the insole 17 and the. bottom lift 18 of the heel. An aperture 19 arranged axially with respect to the recess 16 extends through the insole. A wear plate 20 is placed between the bottom lift 18 and the adjacent portion of the heel to support a coiled" spring 21 which is placed in the housing formed by the recess in the county of Spokane and have invented new plate to be cf 'cess a heel plate located within the shoe above end to the 16. Extending through the aperture 19 is a shank 22 carrying at its lower end a disk 23 and at its upper end a heel supporting plate 24 which, by the action of the spring, is supported a proper distance above the insole.

As shown in Fig. 3, the shank 22 may include a threaded sleeve or nut 25 and threaded stems 26, 27 connected, respectively, with the heel plate 24 and the disk 23. This construction not only facilitates the assemblage of the parts, but it also enables the heel plate to be adjusted at various distances above the insole, as will be readily understood, such adjustment being eflected during the assembling, of the parts.

Under the construction illustrated in Fig. 5, a metallic lining 28 is provided for the recess 16 that constitutes the spring containing housing.

The operation and advantages ofthis invention will be readily understood from the foregoing description, taken in connection with the drawing. The device, ous, may be readily applied to shoes in the process of manufacture; when applied to shoes already made, the bottom lift is removed; a hole is bored through the heel ex-.

tending to the insole, and the latter is provided with an aperture axially with respect to the .bore. The heel assembling member 25 are now placed 1n position, it being obvious that the parts will be assembled in such fashion as to support the heel plate at the desired distance above the insole. The spring 21 is now placed in position beneath the disk where it may be secured in any convenient manner, and the bottom lift 18 is finally restored. The weight of the wearer will depress the heel plate at each step against the tension of the spring 21, thereby producing at each step a resilient action which facilitates walking and promotes the comfort of the wearer.

Having thus described the invention,what

is claimed as new, 1s:-

A shoe having a heel provided with a vertically extending recess and a bottom lift, a compression spring within the recess, an insole provided with an opening therethrough in alinement with the vertical axis of the reand of less diameter than the recess,
